India's Hydrocarbon Outlook – 2022-2023

65 DGH: 3 DECADES OF UNLOCKING INDIA'S HYDROCARBON POTENTIAL wells are fair. Reliability of results is good. Gulf of Mannar has been used as analogue for Kerala sub-basin. Initiated with aerial yield approach, later 3D PSM and Trap Density method have been used to assess hydrocarbon resources due to spread- out data points. Some challenges are poor sub- basalt imaging and sparse seismic coverage. Shelfal areas around Cochin Low in Kerala sub- basin can be focused for future exploration. Long-offset sub-basalt imaging, magneto- telluric, controlled source electromagnetic surveys are recommended. The play-level undiscovered (risked) hydrocarbon inplace for Kerala-Konkan (KK) basin is given below: 303 MMTOE 85 MMTOE 106 MMTOE 62 MMTOE Cenozoic Oligo-Miocene: Cenozoic Eocene (Early): Cenozoic Eocene (Late): Mesozoic Cretaceous (Late): Mesozoic Cretaceous (Early): 46 MMTOE Status, available datasets and opportunities KARNATAKA KERALA TAMIL NADU GOA ANDHRA PRADESH MAHARASHTRA TELANGANA PUDUCHERRY LAKSHADWEEP 0 80 160 240 320 40 KM KERALA KONKAN BASIN LEGEND HELP BLOCK 2D SEISMIC 3D SEISMIC WELLS SEDIMENTARY BASIN SHALLOW WATER BASIN DEEPWATER BASIN DGH Internal In terms of awarded acreage that are now active in Kerala-Konkan (KK) basin, 3,520 sq km are under HELP. As of March 1, 2023, NDR, for Kerala- Konkan (KK) basin has archived 440,987 LKM of 2D seismic data, 14,232 SKM of 3D seismic data, 20 drilled well information. Under OALP Bid Round VIII, one shallow water and another deepwater block with cumulative area of 7,831 sq km has been offered.
